摘要 建立了中立型Emden-Fowler泛函微分方程[r(t)|z'(t)|^(α-1)z'(t)]'+q(t)|x(δ(t))|^(β-1)x(δ(t))=0,t≥t_0的若干新的振动准则,其中,α>0,β>0,z(t)=x(t)+p(t)x(τ(t))。文章得出的结论改进和推广了最近文献的一些熟知的结果。 Some new oscillation criteria are established for functional differential equations of Emden- Fowler type of the form( r( t)| z'( t) |^(α- 1)z'( t)) ' + q( t) | x( δ( t)) |^(β- 1)x( δ( t)) = 0,t≥t_0. Where α 0,β 0,and z( t) = x( t) + p( t) x( τ)). Our results improve and extend some known results in the literature,recently. Several illustrating examples are also provided to show the importance of our results.
